Lauren Conrad -- and her dress -- needed a little help staying up after a night of partying for her 22nd birthday.Cameras snapped her spilling out of her car and her dress as she arrived home from S Bar last night. It was a regular "Hills"-apalooza earlier at Katsuya where TMZ also caught L.C. and Whitney, Audrina and Lo, and ... you know, whoever else.
